Caveats Send documentation comments to [email protected] • CSCsq39683 Symptom: Fibre Channel links with traffic running on it might generate syslog errors such as the following: 2008 May 21 15:08:55 switch %KERN-3-SYSTEM_MSG: FCP_ERRFCP_PORT: gat_fcp_isr_process_blk_intr@1441, jiffies = 0xb1cec:ISR threshold reached, reg_block = 0x8, num_regs = 6, idx = 0, src_bit = 11 - kernel There is no loss in functionality and these messages can be ignored. Workaround: None. • CSCso83662 Symptom: One global MAC address is used in all STP and PVRST frames originating on various ports. This can result in inconsistent MAC moves on peer switches connected with multiple links. Workaround: None. Resolved Caveats-Cisco NX-OS Release 4.0(0)N1(1a) This section lists the resolved caveats for this release. • CSCsq53614 Symptom: Ethernet port channels configured between two Cisco Nexus 5000Series switches cause a memory leak in the DCBX process. This leak eventually leads to the DCBX process crashing and a system reboot (in a few days). This issue occurs only with Ethernet port channels between Cisco Nexus 5000 Series switches. Port channels using the Catalyst 6500 Series switches do not have this problem. Workaround: Disable receive and transmit Link Layer Discovery Protocol (LLDP) on the port channel members by entering the following configuration under each Ethernet interface that is a member of the port channel: Interface Ethernet 1/1 no lldp receive no lldp transmit • CSCsq36609 Symptom: For a virtual Ethernet or virtual Fibre Channel interface configured as a SPAN source, changing the interface administrative state results in a memory leak. Deleting and adding SPAN sessions also causes memory leaks. The memory leaks eventually cause a switch reboot. Workaround: Avoid using virtual Ethernet and virtual Fibre Channel interfaces as SPAN sources. Avoid deleting and adding SPAN sessions. Resolved Caveats-Cisco NX-OS Release 4.0(0)N1(1) This was the first release of Cisco NX-OS for Nexus 5000 Series switches. There are no resolved caveats for this release.
